can you tell me which driver should i install for windows 10 64 bit? i cant install the v5.0.4.43 because windows wont allow the certificate to "pass" only when i do advanced restart while pressing f7 which tell windows to allow drivers without certificate to load, but even then when i test the driver and try copy a big file using usb3, it doesnt copy it in any speed close to what it should.and suggestions?

first of all i imported it an older version of the driver which was imported ok and worked ok after that so there should be a certificate already imported.this is time i ran as an admin that batch file "ImportCertificate.cmd". a screen copy of the message is attached.

is the new certificate is the same as the older one? in other words should the old certificate allow the installation of the new driver?

when i try to install the new driver i get this message in a small box in the device driver: "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52".

the attached picture is after i loaded the new driver using the f7 key in the startup settings (picture attached).as you can see in the picture there is almost no change between usb2 (20 m/sec) to usb3(27 m/sec).what are the speeds that it should get to?

@egozi:Please check, whether the used latest mod+signed Intel USB 3.0 Controller driver has a valid digital signature or not:1. Open the "Controller Driver" sub-folder of the package named "64bit DPInst Set with Intel USB 3.0+3.1 Drivers v5.0.3.42 mod+signed by Fernando":2. Right-click onto the file named iusb3xhc.cat and choose the options "Properties" > "Digital Signatures". 3. Then click onto the content of the Signature list and hit "Details".If the driver has a valid digital signature, you will see a picture like this:

Zitat von egozi im Beitrag #1192But also after installing the driver using Windows advanced startup using the f7 key to load drivers which are not signed, even then the driver didn't work as it should. It was very slow.Any idea?

You should better ask Intel, why this Company doesn't offer any Intel USB 3.0 drivers, which natively do support Win8/8.1 and Win10.

EDIT:

Yes, that is possible.Here is the guide:1. Hit simultaneously the Windows-Key+R.2. Type "certmgr.msc" (without the quotation marks) and hit the "Enter" key.3. Search for the Win-RAID CA Certificate as shown in this picture:4. Right-click onto the listed Win-RAID CA Certificate and choose "delete".5. Don't forget to re-import the Certificate before you are installing any driver, which has been signed by me.
